Texas State Troopers opened fire on two Tuscaloosa residents who they say led them on a 60-mile high-speed chase through a checkpoint near the Mexican border on Wednesday, according to media reports.

Agents tried to search a Ford Explorer occupied by Brian White, 25, and Kayla Smith, 22, at a checkpoint, according to San Antonio news station WOIA. A trooper said that a drug-sniffing dog may have detected drugs in the SUV near a first checkpoint, according to WOIA. The pair continued driving east on U.S. Highway 90, and were able to drive over three traffic spikes placed by law enforcement agents.

The officers reported seeing the couple throwing drugs from the vehicle, according to the news reports.
